<h1>Setting Menu Configuration Properties At Runtime</h1>

<div class="exampleIntro">
	<p>This example demonstrates how to set MenuItem configuration properties at runtime and listen for the changes through the "configChangedEvent."</p>
<p id="clicknote"><em>Note:</em> By default clicking outside of a menu will hide it.  Additionally, menu items without a submenu or a URL to navigate will hide their parent menu when clicked.  Click the "Show Menu" button below to make the menu visible if it is hidden.</p>
